getDigest

public int getDigest(byte[] buffer,
int offset)

Inserts the digest of all the input data since the last reset
into the specified buffer at the given offset.
The digest is then reset.

Parameters:

buffer - The byte array to hold the digest data.

offset - The offset, or initial bit position, to store the data at within the array.

Returns:

An integer representing the number of bytes written to the buffer.
